EMIL WUNDEBLICI-i, OF YORKTOWN, TEX-AS.

COTTON DRIER.

Application filed July 22,

To all whom it may concern:

Be it known that I, EMIL XVUNDnnLIOii, a citizen of the United States,residing at Yorktown, in the county of Dewitt and State of Texas, haveinvented new and useful Improvements in Cotton Driers, of which thefollowing is a specification.

This invention relates to a drying apparatus for drying cotton or othermaterial and. for sterilizing seed and the like, thegeneral' object ofthe invention being to provide a plurality of trays arranged in a dryingcas ing, one above the other, with means for rotating the trays and forcausing the material to drop from one trap upon another after the trayhas made a. revolution so that the material will be subjected to theheat within the casing for a long time while it is passing through thedevice.

Another object of the invention is to make each tray in sections withmeans for dumping a section after it has made a complete revolution.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, refcrence will be had to theac'conipan-ying drawings wherein likecharacters denote like orcorresponding parts throughout the several views, and in which Figure 1is a side view of the device.

Figure 2 is a section on line 2*2 of Fig ure 1.

Figure 3 is a section on line 33 of Fig ure 2. H

Figure 4 is a perspective view of one of the tray sections.

, Figure 5 is a detail view showing a section in dumping position.

Figure 6 is a view of the stationary part for upsetting or dumping atray.

Figure 7 is a View of one of the hub and spoke arrangements of a tray.

In these views, lindicates a casing which is supported on a base 2 andhas a hopper 3 at its top by which material can be fed into the top ofthe casing. The base is provided with a discharge t through which thematerial is taken from the casing. I may pro-' vide positive feeding anddischarge means for the material, though such means are not 1924. SerialNO. 727,5'2'0.

shown as they do not relate to the invention. Posts 5 are arrangedwithin the casing, the posts being connected-together at their upperendsby the pieces 6 and a centrally arranged vertical shaft 7 isjournaled in the base and part 6 and is rotated from a driven shaft 8through means of the worm gear 9. A plurality of trays A are fastened tothe shaft, one above the other, the first tray receiving thematerialdropping from the hopper. Each tray is formed of a plurality ofsections 10, each section being of tapered shape with flanges 11 at itsends so that the sections form a ring-shaped tray with flanges at itsinner and outer circumference.

' Each section is fastened to a rod or spoke 12 which has its inner endfastened to a cupshaped hub member 13 which is fastened to the shaft andthe outer end of each spoke is provided with an angle-shaped arm llwhich carries a roller 15 for engaging an annular track 16, fastened tothe posts 5. Each track is interrupted and one end of the track isplaced at an incline, as shown at 17, so that when the roller drops offthe end 18 of the track and the tray section is tilted by meanshereinafter to be described, the,

roller will strike the inclined part and ride up the same and. thus thetray section will be tilted back to its normal and level position. Inorder to insure tilting of the tray sections I provide 'a' pin 19 forengaging an upright 20 on each spoke 12 when the section reaches the end18 of the track so that the spoke and tray section is given a partialrotary movement to dump the section, as shown in Figure 5. The pin 19 iscarr'ed by an upright 21 whichis fastened to a strip 22 supported by theposts 5, it being understood that a strip 22 and an upright 21 and pin19 are provided for each tray. As shown the spokes pass through holes inthe hubs and are threaded to receive the nuts 21 so that the spokesarerotatably supported by the hubs.

Heat is supplied to the interior of the easing by means of steam or anyother suitable heating medium being passed through the coils 23 whichare arranged within the casing.

From the foregoing it will be seen that the material passing into thecasing through the hopper 3 will fall upon the first tray at a pointjust in front of the inclined part 1'? of the first track sothat thesections re ceiving this material are in flat condition.

it it The material will he carried around with the sections until asection reaches the end 'lFl oi the track when the pin 19 engaging theupright ill and the roller dropping oil the end ot the track will causethe sections to tilt to a substantially vertical position and thus thematerial on this section will be dumped therctroin onto the next tray.As the roller strikes the inclined part 17 oi the traclii it will rideup the same and thus the section will be returned to horizontal or tlatcondition so as to be ready to receive another supply of materialpassing from the hopper. The material dumped from the sections at theany will drop upon the sections at the 2-1 'ond tray and will be carricdaround therewith until the sections oi this t W are dumped and then themate rial nlil. he de aasited upon the third tray l i' this tray it willbe deposited upon the Fourth tray and finally it will he dumped troutthis fourth traj into the outlet nieans. tthus the uaaterial is s-ilon'lr passed through the casing); so that it will be subjected to the heattherein tor a long time and thus it will he tlan'ouc hlg' dried orsterilized. The ac tion is entircliautomatic and the apparatus will needpractically no attention.

it is thought from the 'loreggoine; description that the21tl"tr1li'itltl$ and novel :teaturcs o't' my invention will be readilyapparent.

I desire it to be understood that I may make ehai'lges in theconstruction and in the combination and arrangement of the s-aereralparts, provided that such changes 'l'all within the scope of theappended claims.

li hat I claim is 1- 1. it device of the class described comprising acasing, a vertically arranged shaft t'hereiin a plurality 0t traysattached to the shaft a track associated with each tray, ca ch trackhcine' oi annular construction with its ends spaced apart and with oneend being arranged at an incline, each tray being; composed ct tilt-ablesections, a roller connected with each section and engaging the trackand means For tilt-inc each section as the roller leaves one end oi? thetrack and each section being; returned to lunizontal position by itsroller running up the inclincd portion of the track.

2. A device ct the class described comprising a casing, a verticallyarranged sha l't therein, means for rotating the shaft, 21 plurality oftrays having their hubs connected with the shatt, each tray consistingoi a plurality ot tiltablc sections, a track associated with each tray,a roller connected with each tray section and engaging the track, eachtrack having its ends spaced apart with one and arranged at an inclineso that when a roller engages this inclined part the tray section willbe returned to normal horizontal position, a stationary projection and aprojection on, each section tor striking the same when the sectionreaches the end of he track for tilting the section to dun'ipingposition.

A device of the class described comprising' a casing, a vertieall xarrangz ed sha tt therein having a plurality of trays carried by saidshatt, means tor rotating the shatt, a track associated with iach tray,each trach having its ends spaced apart: with one end arranged at anincline, each tray consisting; of a. tilt-able section and a hubsection, a spoke connected with each section and r0tatably connectedwith the hub section, an angle arm on the outer end of each spoke, aroller carried by the arm for engaging the track, a projection on eachspoke and a stationary projection arranged at the end of each track torengaging the projection on the spoke for moving the tray section todumping posit-ion after which the roller will engage the inclined partof the track so that the tray section is returned to normal horizontalposition.
